EXPANSIVE NUT.

Specification of Letters Patent.

Patented Aug. 2'7, 1907.

A lication filed December 28, 1906. Serial No. 849,876.

To all whom it may concern;

Be it known that I, WALTER R. llfIIiLER, a citizen of the United States,residing at Bellville, in the county of Richland and State of Ohio, haveinvented certain new and useful Improvements in Expansive Nuts, of whichthe following is a specification.

This invention contemplates certain new and useful improvements, inexpansive nuts particularly designed for use on the top posts of buggiesor similar vehicles where the nuts are exposed to considerable jar,although the invention is manifestly not limited to this particular use,and the object of my invention is to provide an improved construction ofnut of this character which will tightly hold itself upon the part towhich it is attached as against accidental displacement.

With this object in view, the invention consists in certainconstructions and arrangements of the parts hereinafter described andparticularly pointed out in the appended claims.

For a full understanding of the invention and the merits thereof andalso to acquire a knowledge of the details of construction and the meansfor effecting the result, reference is to be had to the followingdescription and accompanying drawings, in which:

Figure 1 is a sectional view of my improved expansive nut, showing itapplied to the outer end of a top post of a buggy. Fig. 2 is a face viewof my improved expansive nut, parts of the cap being broken away. Fig. 3is a detail perspective view of a fragment of the nut, showing thesleeve portion of the nut and the remaining portions broken awaytherefrom. Fig. 4 is a detail perspective view of the nut looking at theinner end thereof.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

Referring to the drawing, the numeral 1 designates a belt or similarpart, the outer end of which is threaded to receive my improvedexpansive nut, which is in the present instance intended to embrace theouter end of a top post of a buggy. The nut 2 is preferably made ofthree parts, only, one of which is a hollow body, designated 3, which ispreferably of pressed steel and which is polygonal as shown in Fig. 4,so as to accommodate a wrench or similar tool for turning it. From oneedge of this body there projects a preferably circular flange 4. Asleeve 5 is secured centrally within the body 3, being integral with it,and said sleeve is spaced from the walls of the body proper, as shown,and is provided with end slots 6 and is contracted towards its outerend. The sleeve 5 is provided with a tapered or enlarged entering end 7to receive the end of the post or bolt 1. As is manifest, the slittedend of the sleeve 5 produces spring members adapted to tightly clampupon the bolt, and in addition to th 0 spring function of the sleeve,itself. 1 provide a coil spring 8 which may embody one or moreconvolutions, and which is spread apart so as to press over the end ofthe sleeve far enough to hold itself in place. After being placed inposition, it is evident that the spring 8 will assist the slitted end ofthe sleeve 5 in its spring function, and the coil spring 8 is spacedfrom the walls of the outer portion of the body 3. as best illustratedin Fig. 1. In the present instance, the spring 8 is in the form of asplit washer, that is, a spring with only one convolution, the ends ofthe spring being slightly spaced from each other so as to give thenecessary play, as illustrated in Fig. 2.

9 designates a cap which is flanged around the semicircular fiange 4 ofthe nut so as to close the outer end thereof, as is common with the nutherein set forth.

From the foregoing description in connection with the accompanyingdrawing, it will be seen that I have provided a very simple constructionof expansive nut, which will securely hold the side braces and otherparts of the vehicle top together as against any accidental looseningwhich would otherwise result from the severe jarring to which theseparts are subjectedand which may be used in other connections for thesame purpose.

Having thus described the invention, what is claimed as new is:

1. A nut. consisting of a hollow body, a sleeve secured centrally withinsaid body and spaced from the walls thereof, said sleeve being slittedat one end to form spring members, said members converging from the baseof the nut towards the opposite end of the sleeve, and a springencircling the slitted end of the sleeve and located between the sameand the walls of the hollow body.

2. A nut, consisting of a hollow body provided with a flange, a threadedsleeve secured in said body and spaced from the walls thereof, saidsleeve having a slitted end, a spring encircling said slitted end andlocated between the same and the walls of the hollow body, and a capsecured to said flange and inclosing the slitted end of the sleeve.

In testimony whereof I affix my signature in presence of two witnesses.
